To all whom it may concern: I

Be it known that I, HAROLD L. WVINsoR, a citizen of the United States,residing at Butler, in the county of Bates, State of Missouri, haveinvented certain new and useful Improvements in Hay Sling or ForkReturns; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The present invention is directed to improvements in loaders, and moreparticularly to one for loading hay.

The invention has for its object to construct a device of this characterwhich after discharging its load will be returned automatically toitsloading position.

A further object of the invention is to provide a device of thischaracter which is exceedingly simple in construction, efficient inoperation, and one which can be manufactured at a small cost.

lVith these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in which Figure 1 is a view showing the haysling or fork in a position to unload the hay. Fig. 2 is an enlargedfront view of the drum and reel. Fig. 3 is a sectional view on line 33of Fig. 2. Fig. 1 is a similar view on line 4=1 of Fig. 2. Fig. 5 is asimilar view on line 5-5 of Fig. 1. Fig. 6 is a similar view on line 66of Fig. 1.

Referring to the drawing, the numeral 1 designates a pair of spacedposts, the upper ends of which are connected by a bar 2, and supportedby said bar is a pair of pulley blocks 3 of the usual construction. Oneof the posts 1 is mortised, as at 4, for receiving the bracket 5, saidbracket being bolted in the mortise and provided with bearings 6 forrotatably supporting the shaft 7. Fixed to one end of the shaft 7 is areel 8, which consists of circular side plates 9, the same being held inspaced relation by the bolts 10, to one of which is connected one end ofthe rope 11. The rope 11 has connected thereto a hay sling or fork 12,of any well known construction. The rope 11 passes over the pulley 13carried by the carriage 14:, the same being adapted for travelbackwardly and forwardly upon the track 15, said track being shown inthis instance as suspended in a barn or a like structure. The rope 11thence passes through the pulley block 16, which is suitably supportedin the barn. It will be understood that the rope 11 has one of its endsequipped with a draft appliance so that an animal can be attachedthereto for pulling the rope 11 and fork 12.

Fixed to the shaft 7, and between the bearings 6 is a drum 17 which hasits periphery provided with spiral grooves 18 which are continuous, saidgrooves at their inner terminal being contracted, as at 19, so that thesame opens upon the minor end, of the tapered integrally formed drum 20,the major end of which being provided with spaced flanges 21 which formguideways for the brake shoe 22, which is pivotally mounted for contactwith the drum 20 be tween the flanges 21, said brake being used in caseit is desired to limit the rotary movement of the drums.

A cable 23 is provided and has one of its ends connected to the hook 21, said hook being attached in the outermost groove 18 of the drum 17.The cable 23 is adapted to wind or unwind in the groove 18, and whenwinding thereon the same will finally engage the contracted terminal andwill then wind upon the tapered drum 20, during which time the weight 25will be elevated through the medium of the pulley blocks 3, around whichsaid cable is trained. It will be of course understood that when thecable 23 is winding upon the drums 17 and 20 the rope 11 is unwindingfrom the reel 8, which action imparts rotary movement to said drums. Theweight 25 is preferably formed from a rectangular casing 26, in whichsand or the like may be placed and the lower end of the cable 23 isfixed to the removable cover 27 of the casing, as clearly shown in Fig.6.

When the draft animal draws upon the rope 11, the same will move thefork 12 upwardly until the same engages the carriage 1 1, and continuedstrain upon said rope will cause the carriage to travel upon the track15, and to the point where it is desired to release the load of hay fromthe fork. During the movement of the rope 11, the reel 8 will be rotatedas the rope unwinds therefrom, and during this time the cable 23 will bewinding upon the drum 17, which being greater in circumference than thedrum 20 will exert greater pulling force upon the cable 23 so that theloaded fork will be elevated until it contacts with the assuage 14,

and at which time the weight 25' isyelevated' proportionately. Uponcontinued strain less power is necessary to move the carfiag'e' 14 asthe same travels upon the track 15 with the fork 12 in eega emem;therewith. After' strain has been released from the rope 11,-fthe' w'eig'ht' 2'5 willdescend, which causes the rope 11 to wind uponthe reel andthe cable 23 to unwind first from the drum 20 and then from the drum 17,thereby causilig the ro e 1 1 to return the carriage 1 4; and thegrapple 1 9) to their operative or loading position, as shown in Fig. 1.

It will be' apparent that by forming the drum 1 7 and drum QQ iin themainirer' described the cable" 23 will be unwinding from the drum 20"when the least power is requi regil to return the carriage to the pointon the trackat whichthe fork or sling startsto descend, and that whenthe most power is necessary the cable will have passed from the drum 20and will be unwinding 'from the drum I7, and at which time the zfork orsling will be descending from the track to the load of hay.

upon the rope 11, the cable 23 will wind upon the tapered drum 20, atwhich time a bracket, hearings mounted upon the bracket, a shaftrevolubly mounted in the What is claimed is A device of the classdescribed comprising bearings, a reel fixed to one end of the shaft, adrum fixed to said shaft, said drum ha ing a spiral groove formedtherein, one end of which terminates in a contracted groove, a seconddrum formed integral with the first named drum and being tapered withits minor end adjacent the first named drum, and in contact with thecontracted groove of the other drum. r

testimony whereof, I affix my signature, in the presence of twowitnesses.
